and Sterling Application February 19, 1948, Serial No. 9,556 12 Claims. (M. 123-174) Tins invention relates to an emergency cooling system and is especially adapted for connection with a motor vehicle.

- An object of the invention is to provide a device that will cool on overburdened motor in an automobile or the like.

A further object of the invention is to provide a device that is easily connected to a motor vehicle.

A still iurther object oi the invention is to provide a device where it is possible to quickly provide a storage space for the cooling fluid when it is to be used on the vehicle.

Another object oi the invention is to provide a device that will utilize the fan of the motor to assist in the cooling action.

And still another object of the invention is to provide a remote control means to operate either the cooling system. or the regular fuel supply system.

With the above and other objects in view which will more iully appear, the nature ofthe invention will more clearly be understood by the description and claims, as well as the figures illustrated in the accompanying drawings.

Figure 1 is a side elevation of the front portime of a motor vehicle, with parts broken away to disclose the invention;

Figure 2 is a top plan mounted on the vehicle;

Figure 3 is a perspective view oi the radiator of the vehicle, with the spray means in operative position;

Figure 5 is a top plan view of the invention shown in Figure A, and;

Figure 6 is a vertical sectional view of the spray means taken along line t--t of Figure 3.

Like reference numerals designate correspondview of the invention has parts throughout the several views of thedrawings.

Referring to Figures 1 through 3 and 6, a, motor truck or similar vehicle is indicated generally at it and shows a cab section it, an engine it, a tan it, and a radiator it. A main fuel tank it is mounted in the vehicle in any well-known manner, and a pair of auxiliary fuel tanks 22 and are suitably mounted on the sides of a. truck, or in any manner convenient.

A conduit line it is secured to one of said auxiliary fuel tanks, such as is shown at 22, and terminates at the forward end. of the vehicle,

preferably in close association with the radiator to close valve M too,

it in an annular spray ring suitable perforations 30 radiator. A valve 32, is inserted in conduit line 26 at a point adjacent the fuel tank 22 and a suitable pump 34 is placed in the -line tor a purpose presently to be described. It is to be noted that conduit 28 is connected to tank 22 at its bottom wall, while a similar conduit line 38 is positioned at a slightly higher level.- A cut-off valve 38, similar to valve 82 is placed in the line adjacent the outlet end of tank 22, a filter 40 of substantial size in order to avoid frequent emptying thereof is added to line it near cutofl valve 38. Thus, any sediment or other foreign particles, together with any water entrained in tank 22, will settle out in filter it, prior to entry into the carburetor of the engine. Suitable valves 42 and Ml are supplied in line to to control the flow of gasoline, from tank 22 to auxiliary tank 2d and main fuel tank it. Auxiliary tanks 2t and main tank 28 are connected respectively to fuel line it by means of conduits to and t8 respectively. A second cut-0d valve W is placed in the line after valve it. for use when the fuel supply to the engine it is to be closed. An actuating pump ti is positioned in line it between filter ti! and valve in line 36. Line lit terminates in the carburetor of engine it as is generally indicated at it. A drain-cock it, of usual construction, is located in auxiliary tank 22 and a fuel supply inlet 58 is provided in each oi tanks 22 and it.

Referring to Figure 2, a main switch it is located on the dashboard of the vehicle and controls secondary switches t2 and or. Line t6, leading from switch 62, is connected to pump it on fuel line 36, while line ti leads from switch M to pump it in the coolant supply line it. Both circuits are suitably grounded, as shown at ill.

From the above description, the operation of the device is readily apparent. When it is desired to supply auxiliary cooling water, or the like, to an overtaxed motor on a vehicle, auxiliary tank 22 will be employed to store such fluid. Any gasoline that is in tank 22, will be removed therefrom and sent first to auxiliary tank it and then to main tank 20 by closing master switch it, and secondary switch 62, thus operating pump 52 in line 36. Valve 56 will have been closed, and valve ll will be open. While valve i l may be simultaneously opened, it is generally preferred and permit pump t? to tank 22 and store it 28 provided with on the side facing the remove the gasoline from it to control the flow of fuel.

in auxiliary tank 24 via conduit 46. When tank 24 has been filled, valve 2 is closed and valve 44 is opened to collect the remainder of the fuel left over in tank 22 to be stored in main tank 20. When tank 22 is completely empty, switch 62 is opened and valve 38 is closed. Switch 84 is then closed and pump 84 is energized. Meanwhile, tank 22 will have been filled with water and valve 32 will be opened. Upon operation of pump 34, water is pumped through line 26 and transferred to annular ring 28 to be sprayed upon radiator l8. Obviously, switch 62 will have again been closed in order to supply fuel to carburetor 54. When it is no longer necessary to provide emergency cooling, switch 66 is opened, valve 32 is closed, and drain-cock B is opened to drain all of the remaining water.

In order to insure that any water that may remain on the bottom of tank 22, is not carried over into the fuel supply line, line 36 has been positioned slightly above the bottom of the tank, and may be so constructed that it does not reach to the bottom of the tank, as is usual. Of course, this need not be usually so constructed, since virtually all of the cooling fluid will have drained through drain-cock 5t, and any small amount of water that may travel into the fuel line will settle out in filter 30.

Referring to Figures 4 and 5, there is seen illustrated a simple modification of the device of the invention. In this construction, the feed of cooling fluid is obtained by simple gravity flow, and the necessity for electrical connections is obviated. Thus, a suitable tank, made of rubber or metal, or the like, is positioned on the cab of a truck or automobile and retained thereon by means of suction cups 12. A conduit line it connected to tank it by couplings or the like It leads through the cowl on the vehicle to terminate in the perforated annular spray ring 23 described in connection with the embodiment shown in Figures 1 and 2. A suitable valve 80 is inserted into line H and controls the flow of fluid through the system. A suitable drain-cock 82 is supplied at the lower end of tank It and a suitable inlet means as is provided in the tank.

When it is desired to operate the device, it is merely a matter of filling tank It and opening such as tanks and half-tracks, where the exvalve 80 to supply a spray fluid to radiator is and engine I l.

The fan It on engine l4 assists in the cooling operation by dispensing the cooling spray over the radiator, as well as drawing the fluid through by suction efiect.

Thus, it is readily seen that an emcient and yet simply constructed device has been perfected to cool a super-heated vehicle. This invention is particularly useful where the truck driver is apt to travel through desert sections of the country. Prior to this, heavy laden trucks and over-burdened automobiles, travelling through arid areas or through mountainous terrain frequently overheat their engines and radiators secure water. In addition to being time consuming, it may not always be possible to secure the necessary water and as a result, the driver is forced to depend upon passing traflic for assistance. In the instance where perishables or the like are being transported by truck, such delay may prove to be costly-in both the loss of products and market.

It is to be noted that the device is readily adaptable for use with heavily armored vehicles and as a result, it becomes necessary to stop and Q3 n auxiliary to the main supply,

is in the form of an annular cessive weight and heavy overheat the engine.

While in the foregoing there has been shown and described preferred embodiments of the invention, it is to be understood that minor changes in the details of construction, combination and arrangement of parts may be resorted to without department from the spirit and scope of the invention as claimed.
